Bacterial Transformation

  1. 200 μL chemically- competent E. coli + 5 μL DNA
  2. 30 min on ice
  3. 30 sec @ 42°C
  4. 2 min on ice
  5. add 800 μL SOC
  6. 45 min @ 37°C
    1. spread 200 μL on rich-media plates
    2. → 37°C O/N (inverted)
    3. store remainder @ 4°C
      • spread remaining 800 μL on fresh plates if poor/no growth observed
      • otherwise, discard remainder after ~24h
